iPad Pro as supplemental computing device

I recently bought an iPad Pro (11 inch) as a supplemental device to read pdfs, watch movies, and write notes for class. I’m studying CS so I need a macbook (and frankly prefer it to an iPad by a huge margin) for development tasks. I’m curious how other folks use iPads to supplement their existing devices, as opposed to a solo device. How does the iPad complement and slot into your workflow?
